Robust estimation based nonlinear higher order sliding mode control strategies for PMSG-WECS [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2023 The wind energy conversion systems (WECS) suffer from an intermittent nature of source (wind) and the resulting disparity between power generation and electricity demand. Thus, WECS are required to be operated at maximum power point (MPP).

, 2016 The goal of the chapter is that the reader shall be able to self-dependently make a first, preliminary analysis of wave-induced horizontal forces, motions and mooring tensions for a moored floating wave energy device. Necessary prerequisites to attain that goal are the understanding of the physical phenomena, awareness of simplifying assumptions and ...

Investigation on PTO control of a Combined Axisymmetric Buoy-WEC(CAB-WEC) [PDF]
Ocean Engineering, 2019 The Combined Axisymmetric Buoy (CAB), a vertical axisymmetric buoy, has the potential to deliver a high energy absorption power. Considering the CAB-Wave Energy Converters (WEC), in order to achieve higher efficiency, the Power Take Off (PTO) systems, which converts the float motion into energy output, needs to be properly controlled.
